Interesting thoughts on your site. Thanks for posting.

Do you recall the discussion a couple years ago where one of the extra dimensions was supposed to be large enough to be detectable in the lab, a size similar to the size of neurons? Haven't heard much since about that.

Russell wrote this passage in an era before space travel, so the death of the sun does not seem so catastrophic today—but the death of the entire universe seems inescapable.

In 56 quintillion years, we're all doomed.

I sure hope I'm not alive to see that!

Would please just look at the site and then say what you say? Would posting a link to Sciencedaily, a compilation of links, also be improper.

Everything that is not forbidden is mandatory.

For example, is Andromeda (a nearby galaxy) moving away from our galaxy, or toward it? You have no clue.

It's moving towards us.

IT'S COMING RIGHT FOR US!

I just didn't make the cut.

I guess I do not understand what you are trying to convey? Is it sarcasm? Please enlighten me.

Kind of a vague question. Still, I wasn't part of the discussion if that's what you are asking. More importantly what's your point?

Might be. Supposedly we keep coming back until we get it right. We'll probably be glaring at each other from our respective galactic yard fence even then.

It was very similar to what you mentioned, but if you weren't there then it probably isn't worth digging out the old threads.

Physicists predict that the LHC may create exotic particles like mini-black holes and supersymmetric particles

Errrr.... is this wise????

Is this what you mean?

There has been concern for years that particle colliders might create mini black holes. However, the energy required seemed impossible. Recent developments in string theory have removed the aura of impossibility. Some string theorists now predict that upcoming colliders will be "black hole factories". (Google that quote.) These theorists expect mini black holes to evaporate via Hawking radiation. But Hawking radiation has not been demonstrated experimentally. Five physicists recently estimated the probability that Hawking radiation would work as expected at 50%, 70%, 98%. 99%, and 100%, an average of 83.4%. Another supposed reason not to worry is that cosmic rays in the energy range of upcoming colliders have been hitting the earth (and the moon, where they are more likely to hit heavy atoms) for billions of years without adverse effect. But there is reason to think that a mini black hole would be about as reactive as a neutrino. A mini black hole created by a cosmic ray would retain the momentum of the cosmic ray, distributed over the cosmic ray particle and the earth particle it impacted. It would be moving faster than escape velocity from earth. It would have to accrete many particles to slow below escape velocity, impossibly far out on the Poisson distribution in one pass through earth at neutrino-like rates of impact. On the other hand, a mini black hole created by two particles moving in opposite directions would (sometimes) be moving at less than escape velocity from earth. Depending on its momentum, it would orbit or oscillate within the earth. It would accrete matter at a rate that would be slow initially, but that would increase exponentially.

Why is this not dangerous?

He just proposed a Creator as first cause though simply by postulating an advanced civilization might accomplish what might already have been done.

Because it will be done in France. After it sucks in the first frenchmen, the energy of vomitting them back out will propel the mini-blackhole out of the solar system.

The answer was so obvious!

First cause means an extra-universal, non-physical entity that had to "exist" to create matter. An advanced civilization is a product of matter and therefore is not a First Causer.

I'm no physicist, but doesn't the term "universe" include everything? That being the case, where is there room for a parallel universe? Wouldn't it be included in the first? Just wondering....

Not according to those living in the Universe they created. The Creator could probably pop in into that Universe any time they'd care to do, prepare a planet, create some animals, give some evolutionists hysterics. Maybe the souls of these people are sucked back to the original plane. Let's call that universe heaven. Cosmic theological science. Yum. Obviously God is a pretty advanced being. Likely more advanced than the scientists guessing about him.

I, too, considered this as I tried to disprove Christianity last year.

Logically, it all traces back to a single entity that was beyond the plane the entity created. That is Occam's razor and, since we are equipped with logic, we must use it.
